Y'know you done messed up, right, Scott Disick?
Sofia Richie was filling up Sunday in Bev Hills ... while rocking a midriff-baring top, sure to remind her Scott what he's abs-olutely missing out on these days. Photogs asked her if they've actually broken up, but 19-year-old Sofia was tight-lipped.
As we told you, Scott was all over some chick at Kanye West's album release party last week, and was overheard telling people he's single.
To each his own, but ... damn.
Whoever said revenge is a dish best served cold -- wasn't looking at Sofia pumping gas.
